Application filed November 22, 1921.

To all whom. t may concern.'

Be it known that I, JAMES A. lVA'rT, a subject of the King of GreatBritain, residing at Brooklyn, in the county of Kings and State of NewYork',have invented certain new and useful Improvements in Water--Closet Valves, of which the following is a specification.

y invention relates to float valve for vcontrolling the discharge ofwater from ciswill be especially well adapted for assembllng.

Another very important object of the invention is to construct a deviceof this nature whereby the yieldable portion of the float valve maybemoulded instead of formed by j a blowing process as isthe commonpractice at the present time, thereby greatly reducing the costofmanufacture and increasing the efficiency and accuracy of thisportion.

Another important object lof the invention is to construct a floatvalve, of this nature having all of the advantages found in the commonor coiiventional fioat valve now extensively in use wherein the entirevalve is made of yieldable material, usually rubber.

-A very/special feature of my invention consists in the provision of anefficient and effective clamping mechanism for grasping the edge of thefiexible portion of the valve. lVith the above and ynumerous otherobjects in view, as will appear as the description progresses, thisinvention resides in certain novel features of construction, and thecombination and arrangement of parts as will be hereinafter more fullydescribed and claimed.

In the drawings, Eigure l is a vertical mid-section of my improveddevice, illustrating the preferred embodiment thereof,

Figure 2 is an enlarged detailed section showing the manner in which theclamping device grasps the fiexible member,

Serial No. 516,967.

Figure 3 is an enlargedv detailed section showing themanner in which thetwo clamping sections are drawn together and igure 4 is a section takenon the line 4--4 of Figure 3.

Referring to the drawings in detail it will be seen that the float valveconsists of a cup-shaped seating member of yielding material 1 which isprovided at its edgel with a flange 2 of yielding material preferablyconical shaped and an inverted cup-shaped striifening and supportingmember of rigid e material in the form of a clampin mechanismconsistingof a pair of conica shaped clamping members or cups 3 and 4.

he clamping member or cup 3 is disposed so that its lower or larger endfits within the flange 2. It is to be noted that the diameter of thisend of the clamping member or cup 3 is substantially larger than thediameter of the opening formed by the conical shaped 'flange 2.

An annular groove 5 is preferably ar- V ranged on the exterior of theclamping member- 'or cup 3k adjacent its base edge and a bead 6 isprovided on the interior of the conical shaped fiange 2. This beadI 6aids in holding the inner 'clamp 3 in proper relation to the flange2.while assembling the various parts.

The outer clamping member or cup 4 is .placed over the inner clampingmember or` cup 3 so that an aperture in its apex registers with anaperture in the apexof the inner clamping member or cup 3. A lug 7including a head 7-a and a shank 7 -b is positioned so as to have itsshank pass through these apertures in the clamping members or cups and anut is within the clamping member or cup 3 for receiving'this shank.This lug 7 is provided with an external thread so as to receive the nut8, which is preferably conical shaped, whereby the two clamping membersor cups may be drawn tightly together so as to firmly and positivelygrip and clamp the fiange 2 between their walls as is shown to advantagein Figure 2 and it is to be noted that this clamping action takes placea distance from the edge of the cup-shaped seating member l that is atthe juncture of fiange 2 with seating member l, or at a point within thediameter of the edge of the cupshaped seating member 1. It is also to benoted that the base edge of the inner clamping member or cup 3 issituated closer to the ber provided near its center with means fo; 40
